Projective dimension of powers of cover ideal of Ferrers graphs

Do Trong Hoang, Thanh Vu

Let $λ = (λ_{1}, \dots, λ_{n})$ be a partition with $λ_{1} = m$ . Denote by $J_{λ}$ the cover ideal in the polynomial ring $ S = k[x_1, \ldots, x_n, y_1, \ldots, y_m] $ associated to the…

Unmixed and sequentially Cohen-Macaulay skew tableau ideals

Do Trong Hoang, Thanh Vu

We associate a {\it skew tableau ideal} to each filling of a skew Ferrers diagram with positive integers. We classify all unmixed and sequentially Cohen-Macaulay skew tableau ideal…

Depth and regularity of tableau ideals

Do Trong Hoang, Thanh Vu

We compute the depth and regularity of ideals associated with arbitrary fillings of positive integers to a Young diagram, called the tableau ideals.
